Thanks, James.

I tried with Zerolink off and on, both cases exhibit the same issue. I know that the category is being loaded, because I can debug into the category (having set a breakpoint outside the category) and then step through the category code line by line. But if I set a breakpoint a couple of lines down from where I am, it is ignored. Bizarre.

I'll have to create a small test case and hit bugreporter with it. It's very frustrating. I ended up copying all my code out of the category into the main class just to debug it!

Thanks,
Graham Perks.

I can set a breakpoint in classes and in categories, however XCode will only actually break on the breakpoints in the non-category files.

The breakpoint marker is blue when editing - then the ones in category files turns yellow at launch.

A yellow breakpoint indicates that gdb can't resolve the address. This is usually because the code for the category isn't present at run-time. Make sure you're including the code for the category in your project. (Since categories are inserted dynamically, they don't cause any link errors so it's easy to leave them out of the build then wonder why they aren't working.)


If that's not the problem, disable ZeroLink and see if that improves anything. ZeroLink loads symbols on demand. The debugger doesn't get the debugging information about a module until it's loaded.
